If an eviction action complaint does not meet the statute, assume your eviction action is subject to dismissal by a Plaintiff motion or by the Referee's own gatekeeping analysis. 

File a motion for relief from stay in the BK proceedings to continue the eviction.

Lots of options, just need to know how far along in the process she is and if the bank is working with her or has the bank filed a motion for relief from stay?

Tenant's attorney filed a Discovery Motion in a standard, no pay, eviction.

Your current custodian will need its account number to set the wheels in motion.

I have hardwood floors there, so at $8 S/F, it can hurt.Depending on the damage and call me a crazy cheapskate, but you may not need to remove the drywall and trim if you move fast and get fans, dehumidifiers, etc.

If anyone in interested in partnering up, it would be a way to get going on this, get experienced, and get in motion.
